I am importing my music library from an external hard drive. For some reason, it maxes out and I get a message to clear or delete playlists. I then realized that the system is creating an automatic imported playlist on SOME of my imported library - but not all. I think SONOS is reading the playlist tunes and double counting the songs and then it creates the limit of items i can add.

One - why is this happening. I called and spoke to a SONOS rep and was given some crap about iTunes. This is not an iTunes issue. iTunes isn’t even loaded on my laptop and this is music i downloaded or burned over the years. 

two - can i create more than one library to see if this can be avoided? I have most of my music transferred but it caps out for what I believe is this imported playlist issue
